Looking for Classes / workshops in Los Angeles

I need to finesse my skills with DSLR cameras.
I know the basics.
I work in TV as an editor and I have been on set in countless occasions so I understand lighting, sound, composition etc...
I am looking for some kind of affordable seminar.

Oliver, it's been my experience that the big name seminars for DSLR are often about lighting, composition, how to shoot like a Hollywood cameraman, etc. It sounds like you are looking more for a class specifically on your cameras features? If so, what is the make? Canon does some that are specifically about doing better work with their products. Nikon also.

What specifically do you want to learn more about?
What do you want to shoot? Theatrical? Weddings? Documentaries?

They all require a different set of technical skills. Similar but different.
